Answer to Question 1

Correct Answer: 1
Sodium polystyrene sulfonate (Kayexalate) is given to remove potassium in the patient with acute kidney injury by exchanging sodium for potassium, primarily in the large intestine. It is not used to replace sodium or magnesium, or to exchange calcium for sodium.

Answer to Question 2

Correct Answer: 2, 3
Osmotic diuretics pull extracellular water into the vascular system and increase the glomerular filtration rate (GFR). A test dose may be given and urine output is evaluated for an adequate response. The patient should be assessed for signs of worsening heart failure because of the increased vascular volume that occurs with these medications. Orthostatic hypotension is not an issue due to the increase in intravascular volume but should be assessed when giving loop diuretics. Ototoxicity is a concern with high doses of loop diuretics. There is no documentation that these solutions crystallize.
